Portion of article from today's Tampa Tribune:
"The National Hurricane Center looks at wind speed when rating storms. Some forecasters say pressure is a better measure.
...........Atmospheric pressure, the weight of the atmosphere over a specific point on the earth, is given in millibars, a metric measurement. The lower the pressure at the surface, the more intense the storm.
Normal atmospheric pressure at sea level is roughly 1013 millibars. When Katrina made landfall, its pressure was 920 millibars.
Based on that, Katrina was as strong as Category 5 Hurricane Andrew, which demolished a wide swatch of South Florida in 1992. Andrew was 921 millibars at landfall."
....................
"We certainly welcome other ideas in the marketplace of ideas," Hurricane Center spokesman Frank Lepore said. "Write it up then publish it and then give other scientists a crack at it. Eventually the truth comes out."

Interesting article.
Learn from the past, do not dwell on it.
